In this paper, we propose a methodology for embedding a color image data into a PDF file and vice versa. At the transmitter, the signature image is encoded by encryption algorithm. When host file is an image, the information is embedded in the host image in the red components. Furthermore, this scheme requires no knowledge of the original image for the recovery of the signature image. At the receiver, the decryption algorithm reconstructs the original signature file by decrypting the password in the stego-file then by decrypting the secret message out of the stego-file. Simulation results show that data embedding based on coding process followed has no visible distortions in the host image. The results for the proposed work are obtained using the MATLAB version 7.10.0.499(R2010a).
